Matter, 3112 NE. 46th Ave, Portland, Greg. Iiied Apr. 9, I962, Ser. No. 185,937 2 Claims. (Cl. 220-52) My inventionrelates to a means of guiding a container cover retaining strip whilethe strip is being: removed from the container and cover and is woundonto a conventional key of the type having a hand piece at one end of awinding stern and a slot in the stem near its other end and is adaptedfor that purpose.

An object of this invention is to guide a container cover retainingstrip while being wound onto a conventional key adapted to remove thestrip rfrom the container and cover.

Another object of this invention is to provide a means in conjunctionwith a conventional key adapted .to remove a container cover retainingstrip from the container and cover whereby the operative position of thekey in relation to the strip can vary while the strip is removed evenlyand wound onto the key uniformly.

Another object is to provide a retaining strip guide adapted for use inconjunction with a conventional strip removing key of the type having ahand piece at one end of a winding stem and a slot in the stem near itsother end, the retaining strip guide being removable from the keywinding stem and the retaining strip which has been wound onto the stemafter being removed from the container and its cover, the entire key,with the retaining strip wound onto the stem is discarded after beingonce used, but the retaining strip guide is available for use inconjunction with other conventional keys.

Further objects and advantages of the invention will appear in and fromthe following specification considered in connection with theaccompanying drawings, which are for purpose of illustration and notintended as a definition of the invention, the invention being definedin the appended claims.

Referring to the numerals on the drawings:

The container cover retaining strip guide, as shown in FIGS. I to IXinclusive, comprises side walls 1 and end walls 2 with a guide opening 3therebetween, the width of the opening 3, between the side walls 1, issubstantially equal to or slightly greater than the width of the coverretaining strip 22, the side walls 1 are provided with openings 4therethrough to permit the insertion of the stem 1!) of a key 11 adaptedfor the removal of the container cover retaining strip 22, the guideopening 3 extends across and out from two sides of the key stem 10 tothe end walls 2.

The form of strip guide shown in FIGS. X to X'III inclusive is the sameas the form disclosed in FIGS. I to IX inclusive and with the additionof the guide arm 5 extending upward from the end wall 2 which is at theforward or leading end of the strip guide when the retaining strip isbeing removed from the container and its cover, the upper end portion ofthe guide arm 5 is adapted to rest on the top edge 20- of the cover ofthe container 21 while the retaining strip 22 is being removed asillustrated in FIG. XIII. The guide arm 5 being at the foreward end ofthe strip guide results in the guide arm 5 maintaining its position inrelation to the container regardless of the diameter of the retainingstrip 22 being accumulated on the key stem 10*. As illustrated in FIG.VI both the forward end and the rearward end of the strip guide areagainst the container 21 when the key is starting to remove theretaining strip 2 2 from the container but, as illustrated in FIGS. IX,as the removed retaining strip 22. accumulates on the stem 10' therearward end of the strip guide is :forced away from the container whilethe forward end is always in contact with the container wall therebymaintaining the position of the guide arm at all times, in relation tothe wall of the container 21. l V

The form of strip guide shown in FIGS. XIV to XVI-II inclusive issimilar to the structure disclosed in FIGS. I to IX inclusive, butwithout the openings 4 in the side walls 1, and comprises side walls 1and end walls 2 with an opening 3 therebetween and has arms 6 extendingout ward from the side walls 1, the arms 6 permit the stem it) of thekey 11 to bear against the arms 6 and force the strip guide to move withthe key 1'1 when in operation.

The form of strip guide shown in FIGS. XIX and XX comprises side walls1, end wall 2 with guide opening 3 therebetween, the side walls 1 areprovided with openings 4' therethrough to permit the insertion of thestem 10 of a key 11 adapted for removal of the container cover retainingstrip 22, the guide opening 3- extends across and out from one side ofthe key stem 10 to the end wall 2.

When a well known and widely used conventional key, such as the typeillustrated in the drawings, is used, without the strip guide, to removethe cover retaining strip 22 from a container 21 and during all of theoperation the key is held in proper alignment in relation to the strip22 being removed, the strip 22 will be removed evenly and will be wounduniformly around the stem 10 of the key 11 but, if the key isinadvertently operated out of alignment in relation to the retainingstrip 22, the strip 22 tends to wind around the key stem 10 in a lisphazard manner and gradually run ofi the end of the key stem 10 andrender the key useless to complete the operation, or will cause theretaining strip 22 to be torn across its width and thus require meansother than the key to remove the remaining portion of the retainingstrip 22.

When removing the cover retaining strip 22 with the same key inconjunction with the strip guide, as illustrated in the drawings, thekey stem 16* is inserted into the openings 4 in the side walls 1 of thestrip guide, as illustrated in FIGS. IV to IX inclusive, with the slot12 between the .two side walls 1 and the starting end of the retainingstrip 22 inserted into the slot 21 in the stem 10 of the key 11, seeFIG. IV, the stem 10' then being rotated to remove the strip 22 from thecontainer 21 and wind it onto the stem 10 of the key 11 as shown inFIGS. VII-VIII and IX. The strip 22 is wound uniformly onto the stem 10,the side walls 1 of the strip guide hold the strip in a straight linewhile being wound onto the stem 10 and it would be impossible for thestrip 22 to wind itself off the end of the stem 10.

It has also been determined, by actual demonstration, that when the key11 is operated in conjunction with the strip guide, as illustrated, andthe key is inadvertently held at a substantial angle, from the positionshown in the drawings relative to the retaining strip 22, the strip 22will wind evenly onto the stem 10 and does not tear the strip 22 acrossits width while the strip 22 is being removed from around the container21.

When removing the cover retaining strip 22 with the conventional key inconjunction with the strip guide of the structure, as illustrated inFIGS. XIV to XVIII inelusive, the winding stem 10 is positioned to bearagainst the back side of the arms 6 and above the side walls 1 with theslot 12 in the winding stem positioned over the opening 3 and with thestarting end of the strip 22 inserted into the slot 12 the winding stem10 is rotated and the retaining strip is removed from the container andwound evenly onto the Winding stem 10, the strip 22 being guided ontothe winding stem 10 by the side walls -1 and the inner surface of thearms 6.

As illustrated in FIGS. I to XIII inclusive and in FIGS. XIX and XX, thestrip guide becomes non-removable from the winding stem it? of the key11 after the strip 22 is wound onto the winding stem 10 and thereforethe conventional key and the retaining strip guide are discarded atterbeing once used.

The retaining strip guide illustrated in FIGS. XIV to XVIII inclusivecan be removed from the winding stem 10 and the retaining strip 22 whichhas been wound around the winding stem 1i? and only the conventional key11, with the retaining strip wound on the stern it will be discardedafter having been used once and the strip guide can be used again onother conventional keys.

Although I have illustrated and described various embodiments of myinvention, I do not intend to be limited to the speciiic disclosurescontained herein since various changes, modifications and substitutionsmay be incorporated in the embodiments disclosed without departing [fromthe spirit of the invention and I hereby reserve the right to all suchchanges, modifications and substitutions as properly come within thescope of the appended claims.
